chockfull of knowledge
This is the most carefully researched compendium of pagan herbal lore I've ever found. He has everything in here from the botanicals themselves to astrological correspondences to powers attributed to the plants and their parts. And to his credit, he has appendices in this book to cross-reference all of the information contained in the encyclopedic body of the book. His bibliography is also very valuable as he gives astute advice and observations on some of these resources, such as the Golden Bough ("Take with a large grain of salt"). I still refer to this book regularly and I've had it 10 yrs now. Excellent scholarship and of interest whether you are pagan or not, whether you are Wicca or Witch (and thank you, Scott, for giving us the difference between Wiccans and Witches in your glossary). Mr. Cunningham left us a wonderful legacy of practical pagan resources in his books.
